Anyone have any advice/objection to me gently scraping off the uncolonised verm and replacing it with some CVG?
How was the verm prepped?

Verm was brought to field capacity then placed on top of the RGS with no other techniques. Whenever it got too dry I misted it (usually once-twice a day).
The RGS bottles have been in the SGFC for 8 days and they're not doing anything at all.

The verm is probably hosting bacteria. Verm needs pasteurization at minimum

Hmmm I've used verm right out of the bag. It just sucks as a casing layer on it's own plus it's just cased grain, so there's probably not much water in there either

So dunk, drain, then re-case with bucket tek'd CVG?
If it fucks up, whatever. Better to try and at least learn something, yes?

Verm is just not that great as a casing layer on it's own, but it works. Not sure what your exact issue is, I mainly commented to note that I've used verm right out the bag many times.
Like after doing a bucket of cvg, if it seems it's a little too wet I'll just throw a little more verm from the bag in there

I recommend you guys look into verm and bacteria

Well I've scraped off the verm and I'm dunking them at the moment so I'll drain them soon and then re-case with bucket tek'd CVG. We'll see what happens in a week

Verm is an inert mineral so I can't fathom why it would inherently have bacteria on/in it. It's an expanded rock done under intense heat and then bagged, I'm pretty sure it's damn near sterile when it gets to you

After 2 seconds of searching I found this quote from RR

A combination of buffered peat/verm will outperform plain verm. RR

None of the bottles smelled bad at all, nor did they have any "ice creamy" mycelium, but I'm not an expert at spotting bacteria yet.
Regardless, they have had the vermiculite removed, dunked, and re-cased with field capacity CVG. I hope it works out, but if not, oh well!
At least I learned not to case with plain verm, I just thought all the holes in it would be good for a pinning environment and holding humidity close (kinda like with PF cakes).

And actual research, off site. Am I misunderstanding this? https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.sciencedirect.com/science/article/pii/S0016706109002353&ved=0ahUKEwiUuYDJ9PnSAhUhjVQKHSu1A0kQFggtMAQ&usg=AFQjCNFRxcDsjlNc0AfOzBtxeDbA6hA9cw&sig2=bRwXcyto2vcg0IAs1XPumQ

Yes, you are. That article is about the effects of bacteria on vermiculite, not that vermiculite inherently has bacteria. They add bacteria to verm to see if the different strains of pseudomonas, which were genetically engineered by the scientists to differ from each other in one gene only, affect clay aggregate in different ways.
We use verm for a lot of stuff in construction so it's useful to know. Only one strain of pseudomonas in that study is Wild Type, meaning unaltered, the rest are genetically altered and definitely not found in verm naturally.

But they found bacteria not introduced by man?

Reread that abstract man. They introduced all strains, including the Wild Type strain, in order to see how the bacteria processes minerals in verm. They didn't find any bacteria, they added it.
Quote:
Using bacteria of the strain Pseudomonas fluorescens wild type CHA0 and its genetic derivative strains CHA631, CHA77, CHA89, CHA400, CHA661 (which differ in one gene only) the changes in chemical, mineralogical and rheological properties of the clay mineral vermiculite affected by microbial activity were studied in order to test whether the individually different production of metabolites by the genetically engineered strains may alter the clay mineral vermiculite in distinct ways
That is the point of their experiment right there. The rest of the article is on their findings.

I still wouldn't use it with anything less than pasteurization though
